Calm.com is a web site that offers peaceful scenery and guided relaxation directly from your web browser. Just decide what environment you want to look at, how long you want your break to be, and stare at the screen to let your troubles fade away.

Basically, it's like quick meditation for the busy worker. You can simply stare at the relaxing video loops it provides or the site can guide you through a relaxation exercise. It's not only a good way to quickly refresh during the work day, but put your busy mind to rest before you go to bed. Despite the site's singular function, it gives you plenty of control over scenery and sound so your break works exactly as you want it. Plus, Calm.com is completely free to use.
